HYDROCARBON-VAPOR BURNER.

SPECIFICATION formingpart of Letters Patent N O. 703,591, dated July 1, 1902.

Application filed February 18,1902. Serial No. 94.583. (No model.)

My invention has relation to a burner fork 1o consuming liquid fuel, such as hydrocarbons,

and in such connection it relates to the construction and arrangement of the parts constituting such a burner. Y

The principal object of my invention is to 15 provide a burner for hydrocarbon or similar liquid fuel in which alarge body of fiame can be produced and in which the volume or body of the llame can be regulated to suit varying conditions of Work. Y

My invention consists, first, in so disposing the burner proper within a surrounding delector that a vertical adjustment of the burner within the deflector simultaneouslyv varies the amount of exposure of the flame of the yburner with regard to the delector and the opening controlling the supply of vapor or fuel to the burner, and, second, in making the surrounding deilector in such a construction hollow and a part of the vapo.

rizing apparatus for the burner.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a vertical'sectional view of aA burner embodying main features of my invention. Fig. 2 is a horizontal sectional view taken on the line 2 2 of Fig. l, and Fig. 3 is a. side elevational View of the burner.

In the drawings the burner is illustrated as adapted to be supplied with petroleum or similar hydrocarbon fuels and to be used in the generation of steam in a motor-car; but such special use is'not the only use to which from the spirit of my invention.

Referring to the drawings, a represents a vaporizing-chamber mounted upon the upper end of a casing b. The interior d of the chamber a is preferably annular and in cross- .section is triangular, having an inner inclined the burner may be put without departingy or conical face g. Within the casing b and surrounded by the vaporizing-chamber a is arranged the circular burner o. The fuel is supplied by a pipe d t-o the interior d of the vaporizer a and flows in a circuitous path throughv the same and `into a coil or ring e,

situated above the vaporizer a and burner c.

y The vapor from the'coil or ring e is fed to a burner-hozzlef at the lower part or base of vthe casing b. 'Thecircular burner c has a series of outlet-jets projecting toward the conical detlecting-face g of the vaporizer, so that the flame from the burner may strike said del'ecting-face g. The burner c is so arranged that it may be moved up or down within the deecti'ng-face g, so that its jets may be more or less covered by said face g, according to the movement of the burner c. The burner C is preferably made inthe form of a circular chamber having a central hollow spindle h, constituting the induction and mixing chamber for the burner. l zlefpasses upward in the spindle h, and in its passage air is sucked with it through theI .annular head ofthe burner c projects a flange 7c, which works up and down in a guide-ring Z, formed by the casing b. A shoulder m at the base of the annular chamber of the burner c rests upon the ring l when the burner cis in its lowermost position. Through the hollow spindle or stem h of the burner is passed a needle-like cone n, which enters into the vapor-nozzle f to close or regulate the flow through said nozzle finto the spindle h. The needle-cone n is supported byk and travels with the burner c,.so that a movement up or down of said burner c'will cause the cone n to retract from or enter more tightly in the vapor-nozzle j".

In the operation of the burner if the stem or spindle h, with the annular head of the burner, be raised the jets from thevburner The vapor from the nozl will clear, more or less, the dellector-chamber d, and a larger volume of flame issuing from the burner will result. At the same time the lifting of the annular' burner-head will raise the cone n from the vapor-nozzle, and hence a larger supply of vapor and air will enter the spindle and burner-head, causing more llame and more heat to issue from the burner.

The vaporizer a is connected conveniently to the guide-ring l of the casing b by means of studs o or the like, which permit the vaporizer to be removed from the casing, if desired, and also isolate or separate the vaporizer from said casing. The nozzlefis preferably formed upon a bracket or branch pipep, supported by the casing b, and the bracket or pipe b is coupled directly to the outletpipe of the coil e. Under the annular vaporizing-chamber d is mounted a dish or other receptacle q, into which methylated spirits or the like maybe introduced and burned at the initial starting of the vaporizer. At the lower end of the casing b and below the outlet from the nozzlefis arranged a drip-trough t, having an outlet-pipe r for delivering the waste accumulating beneath the stem of the burner. The annular head c of the burner and the supporting hollow spindle h thereof are separated by circular openings or holes S, through which air may pass to the center of the flame, thus causing the flame to issue from the burner as a ring-like body with a hollow center or core.

llaving thus described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a hydrocarbon or similar burner, an annular burner-head, a stationary annular vaporziug-chainber surrounding the burnerhead, the face of said chamber adjacent to the lmrner-head being arranged to deflect the flame from said burner-head, a vapor-nozzle located below the burner-head, a needle-cone carried bysaid burner-head and entering the vapor-nozzle, and means for elevating the burner-head to simultaneously lift the burnersurface above the dellecting-face of the vaporizer and to elevate the needle-cone from the vapor-nozzle.

2. In a hydrocarbon or similar burner, a vapor-nozzle,a n eedle-valve controllingsaid nozzie, a burner-head carrying said needle-valve, an inclined. deflector-plate surrounding the burner-head, and means for elevating the burner-head to thereby simultaneously elevate the needle-valve and cause the burnerhead to clear the deflector-plate.

3. A hydrocarbon or similar burner, comprising a movable annular burner-head, a stationary annular vaporizingchamber surrounding said head and having a flame-delecting surface on that side adjacent to the burner-head, a vaporizing-coil passing from the chamber in a convolution above the burnerhead,a vapor-supply nozzle located below the burner-head and connected with said coil, a hollow stern supporting the burnerhead and surrounding the vapor-nozzle, a stationary guide for said stem, a needle-regulator carried by the burner-head and entering and engaging the opening in the vapornozzle, and means for imparting vertical movement to the hollow stem, burner-head and needle-regulator.

4. A hydrocarbon or similar burner, comprisinga movable annular burner-head, astationary annular vaporizingchamber surrounding said head and having a llame-delecting surface adjacent to the burner-head, a vaporizing-coil passing from the chamber in a convolution above the burner-head, a vapor-supply nozzle located below the burnerhead and connected with said coil, a hollow stem supporting the burner-head and surrounding the vapor-nozzle, a stationary guide for said stem, a needle-regulator carried by the burner-head and entering and engaging the opening in the vapor-nozzle, means for imparting vertical movement to the hollow stem, burner-head and needle-regulator, and a drip-trough surrounding the base of the vapor-nozzle.

In witness whereof I have hereunto set my hand in presence of two witnesses.

JOHN JOHNSTON.
